← TechnologyWhich limitation results from exceeding rated air turbine speed?
A)Generator over-voltage increases rapidly✓
B)Yaw system becomes unresponsive
C)Blade stall reduces efficiency
D)Icing risk on the nacelle lowers
💡 Explanation
Uncontrolled acceleration increases generator rotor speed, so unwanted *magnetic saturation* creates excessive voltage peaks because flux generation becomes nonlinear; therefore voltage rapidly increases, rather than producing stall or icing scenarios.
